Abstract (en)

[origin: WO0142797A1] The invention relates to a micromechanical structure, in particular for an acceleration sensor, comprising: a substrate (1) which has an anchoring device; and a centrifugal mass (5) which is connected to the anchoring device via a spiral spring device (4a-d), in such a way that the centrifugal mass (5) can be elastically deflected out of its resting position. The centrifugal mass (5) has an elongated convex shape and is substantially rotationally symmetrical in relation to the longitudinal axis (L). Optionally, the centrifugal mass (5) has widened sections (5a, 5b) at both longitudinal ends, onto which the spiral spring device (4a-d) is mounted.
